What is a Dacia 1304 I airbag control unit?
The Dacia 1304 I airbag control unit is the central safety unit in the vehicle, activating all occupant restraint systems in the event of an accident. It continuously monitors relevant sensors, stores important crash data, and ensures the proper function and deployment of all connected airbag modules and seatbelt pretensioners to maximize occupant safety.
This safety-relevant electronic module is responsible for controlling and monitoring the entire passive safety system.
It processes signals from impact sensors and triggers the airbags and belt tensioners if necessary.
Why is the Dacia 1304 I airbag control unit defective?
A Dacia 1304 I airbag control unit can be defective due to internal electronic damage, software errors, or crash data stored in an accident that prevents normal functioning. This often leads to the airbag warning light illuminating and requires a professional Dacia 1304 I airbag control unit repair.
Common causes are age-related wear and tear of components, overvoltage in the vehicle electrical system or moisture ingress.
Even after a minor impact, crash data can be stored in the control unit, even if the airbags have not been deployed.
In such cases, the control unit must be reset or replaced to correct the error.
